In other news.....Covid-19 has mutated once again......this time in the UK....and nobody knows if the newly approved Pfizer and Moderna vaccines are effective against it.

Great. Wonderful news. Say hello to 2021.

While it is a cause for concern, we shouldn't panic about this.

Apparently it's highly likely existing vaccines will still work against it, and even if it does mutate to evade them, now that we have a working base vaccine it is easy to tweak it to account for new mutations, just like we do for seasonal flu.
